from the sending-a-signal-to-use-signal dept.

The Signal messaging progam is now the favored messaging program for the European Commission instead of proprietary messaging programs. The decision was made last month, in February, to prefer it for both internal and external communication.

The Signal open source software is written in JavaScript, TypeScript and CSS and published on GitHub under a General Public Licence v3.0[*] (GPLv3). In particular, the clients are published under the GPLv3 license, while the server code is published under the GNU Affero General Public License v3. The software contains the following features:

  • Voice and video calls to other Signal users;
  • Text messages, files, voice notes, pictures, GIFs, and video messages to other Signal users;
  • Group messaging;
  • Set deletion timers for messages on both the sender and the received devices.

All communications to other Signal users are free of charge and automatically end-to-end encrypted.

    Matrix is open source, federated, and also has E2E encryption (also OTR-based like Signal). I set it up recently and it's definitely in need of some polish, but it works.

    The initial bootstrap for Tox is NOT decentralized, since you have to get the initial DHT from somewhere, but after that it goes user to user or user relay user with only key, endpoint and packet data visible to the relays if you are not operating peer to peer over clearnet. Given the dangers of servers shutting down in the federation sense, I think Tox's system adds more portability if more people were to run their own relays, and more apps had a slot in them for adding priority relays (currently you have to add them in the tox.ini file manually which is obviously beyond most modern day users, leaving metadata connecting user accounts available.)
